I hope someone can tell me what to do or what is wrong with my Beta.
I've had him almost 2 years he lives alone in a 1.5 - 2 gallon tank without a filtration system and fake plants. I do water changes 2 times a week. I've noticed over the past several weeks a condition that is worsening it appears as though something has taken a bite out of back (top edge mid back region). What would cause this?? Please help.
Thanks, Beta Mom

Thanks, I was wondering if it could be the plastic plant. Since I wrote the post I went to Petsmart and they suggested Quick Cure, a total water change and putting him into a new container. Today I put him into an new 1 gallon vase with no stones or plants and 1 drop of Quick Cure. I will write a post again in a week to let you know his progress. :)

You might want to look into having a bigger tank for him to actually live in like a 2.5 gallon or something. Makes water changes easier (you can do partial changes instead of full) and even that little bit of a bigger size keeps the tank a little more stable than a 1-1.5 gallon will. Do you use a heater with him?

Also, instead of plastic plants they sell silk ones that I really like to use with everyone, not just just my bettas...those won't hurt your betta and you might find him sleeping or resting in them :)
